To all whom it may concern:

Be it known that 1, MICHAEL F. BRocAN, a citizen of the United States,residing at Lawrence, in the county of Essex and Commonwealth ofMassachusetts, have invented Certain Improvements in Cementing-Machines, of which the following description, in connection with theaccompanying drawings, is a specification, like reference characters onthe drawings indicating like parts in. the several figures.

This invention relates to machines for applying cement or the like tostock and is illustrated in connection with a machine for cementingsoles, taps, or other pieces of stock.

In the manufacture of boots and shoes it is sometimes desirable to applycement to piece of stock and at other times to both sides.

One feature of the invention comprises a cementing machine havingcooperating rolls, means for supplying cement to said rolls, and valvesfor selectively varying the amount of cement supplied to said rolls.With this construction a desired amount of cement may be supplied toboth rolls whereby cement is applied to both sides of the stock, or onevalve maybe closed so that cement is applied to one side only of thestock.

Another feature of the invention comprises a valve located in proximityto the cement applying roll and having a planed side' past which thecement flows when said valve is open, the edge of the valve serving todistribute the cement to the roll.

These [and other features of the invention, including certain details ofconstruction and combinations of parts will be explained in thefollowing description and pointed out in the claims.

Figure 1 is a side elevation of a machine embodying the invention invthe best form now known to me; Fig. 2 is a perspective view; Fig. 3 isan end view; Fig. 4 is a detail; Fig. 5 shows a sole having the shankskived; Fig. 6 shows a molded sole.

The frame 2 supports the driving shaft 4 provided with fast and loosepulleys and carrying the upper roll 5. A counter-shaft 6 is connectedwith shaft 4 by gearing and carries the lower roll 8 so that both rollsare positively driven. Cement is supplied to the upper roll from a tank10 carried on brackets 12, as shown in Fig. 3, and having a centraldepending portion with downwardly Specification of Letters Patent.

inclined side walls in the base of which is formed an outlet in which ismounted a controlling device 15. This device comprises a shaft, the endportions of which are cylindrical, as shown in Fig. 4, to turn inbearings in the tank. The portions intermediate the end portions andwhich are located in the discharge opening are cut away on a chord toform the plane face at 16. The discharge opening is so shaped withrelation to the shaft that it is completely filled and closed except forthe opening afforded by the cut-away portion when the shaft ispositioned as shown in Fig. 3, and by turning the shaft more or less thewidth of the outlet may be varied to regulate the discharge of cement. Aplate 17 fast on the shaft and having an are shaped slot into whichprojects a fixed stud on the tank limits the movement of the shaft andindicates when the outlet is closed. The shaft stands substantially incontact with the periphery of the roll 5 and serves not only'as a valveor device for controllingthe delivery of cement but also as a.

distributing device for spreading the cement. A scraper 18 is supportedat the rear of the roll 5 to remove any foreign material that may havebeen picked up by the roll. The roll comprises a hub of suitablematerial by which it is rotatably secured to the shaft, and a bodyportion or thick covering of soft rubber, the acting face of which isdeeply corrugated, and preferably the corrugations are formed byalternate grooves and ribs extending at right angles to the direction ofrotary movement, the ribs having angular outer edges.

It is found in practice that a roll constructed as described will carrythe amount of cement necessary for thickly coating the sole preparatoryto laying the sole or applying it to the shoe bottom. The cement servesboth as a temporary securing means and also to exclude moisture from theconnection between the sole and the portions of the shoe adjacent to it.This construction also has the advantage, because ofits yieldingcharacter, that it will apply a suitable coating of cement to the entiresurface of the sole the shank of which is skived at the edges, as shownin Fig. 5, the relatively high portions sinkinginto the soft rubber andyet receiving their proper coating of cement which is carried in thegrooves between the ribs on the roll. Another advantage due to PatentedJune 11, 1915.

the use of the soft, corrugated cement-applying roll,- and preferably asupporting roll 8 of similar formation is that a sole which has beenmolded to the shape of the shoe bottom, as, for example, to the shapeshown in Fig. 6, can be cemented without disadvantageously affecting itsshape.

As above suggested, the supporting roll 8 is formed like the upper roll5 with a thick body portion of softrubber into which the article beingcoated may be deeply embedded without the use of pressure that wouldstraighten out a molded sole or that would prevent cement being properlyapplied to the higl1 portions of the article. For further adapting themachine to accommodate articles differing in thickness or havingirregular shapes the supporting roll together with its shaft, isarranged upon a yieldingly supported frame 20 which is pivotallyconnected to a rod 22 that is rigid with the frame of the machine.Arranged in operative relation to the roll are tables 24, 25, the latterof which has a ribbed surface as shown to receive the cementcoatedsoles. These tables are both mounted upon the yieldingly supported frame20 so that they maintain'a constant relation to the supporting roll asits frame yields up and down. The frame 20rests at its rear end upon'aspring 26 through which extends a stud28-having a wing nut 'by which thenormal position of the roll may be varied. Provision is made forsupplying the supporting roll 8 with cement or other material which mayor may not be like the cement or other material with which the upperroll is supplied. To this end a tank 30 is pro- 1 vided which issupported by the rod 22 and by a connection to a tube 32 with a cementdelivering member 34 arranged lengthwise under the roll 8 and secured indefinite relation to the frame 20 and to the'periphery of the roll. Thedelivering member 34 is provided with a controlling device 35, like thedevice 15-before described. The relation of these devices to their rollsis disclosed in Fig3 in which portions are broken away for that purpose.By reason of the arrangement shown the supporting roll 8 may moveautomatically as the work varies in thickness or be adjusted intodifferent relations to the roll 5 without disturbing its connection withthe parts which supply it with cement or varying in any way the deliveryof cement to it or the application of cement to the stock. The tube 32is provided with an elbow as shown in Fig. 3; and, through the'underwall of said tube at said elbow, is threaded a drain-plug 37. It is thuspossible to shut oil from either roll the supply of cement and to drainthe lower tank, if desired.

Scrapers 40 are provided atopposite ends of each roll to engage theedges of the periphery of the roll and wipe the cement away from the endof the roll.

Having explained the nature of this invention and described aconstruction em- .bodying the same, I claim as new and desire tso secureby Letters Patent of the United tates:

1. In a cementing machine, the combina-- tion with a cement reservoirand a cement applying roll, of a device for controlling the flow anddistribution of cement arranged in close proximity to the roll andcomprising a shaft having a planed side and adapted to be adjusted topermit the cement to flow past said planed side and to be distributedupon the roll by one edge thereof.

2. In a cementing machine, the combinav.tion with a cement applying rolland a supporting roll, and a yieldingly upheld frame pivoted at one sideof the supporting roll and provided with bearings for said roll, oftables arranged at either side of said roll and supported by 'the framewhereby they arpl maintained in constant relation to the re I 3. Acementing machine having. in combination, a roll, a cooperating roll,means for supplying cement to said rolls, and valves for selectivelyvarying the amount of cementsupplied to said rolls.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
